灯光再亮暖不了你的心城市再闹唤不醒你的情
[dēng guāng zài liàng nuăn bù le nĭ de xīn chéng shì zài nào huàn bù xĭng nĭ de qíng]
This means 'Bright light cannot warm your heart, even if the city is bustling, it won’t arouse your emotion', suggesting deep-seated emotional disconnect or detachment despite external stimuli and interactions intended to reach or excite you emotionally.
